Notice anything missing from these?
Keen eyes would note that not a single one of these makes a note of one important thing: *how often the email can be expected to be received.*
### Why this is important
People are, more now than ever, protective of their email inboxes. So not only will they be super-cautious about they sign up for, they will want to know how often they can expect to hear from you / your organization. After all, who wants an email newsletter every day when there are [clearly better things to do](http://www.portlandtimbers.com/)? Some of the examples above don't even tell the user what sort of information they can expect in their inbox once they do start receiving emails. Will it be tips? Recipes? Announcements? News about the company? Discounts?
So, when including a subscribe form on your site, make it clear what the email will be about and how often you're going to send it. Not only will you be saving people time, you'll be further targeting your audience.
